T at whom it may concern.-

Be it known that I, CHRISTIAN FRIEDERICH,

a citizen of the United States, residing at Elizabeth, in the county ofUnion and State of New Jersey, have invented certain new and usefulImprovements in Oop-WVinding Machines, of which the following is aspecification, reference being had therein to the accompanying drawings.

Myinvention has for its object to provide a machine of simpleconstruction by which flat or disk-formed cops of thread, moreespecially adapted for use in sewing machine shuttles, maybecontinuously and automatically wound I 5 on a machine which, upon thecompletion of a cop, will be automatically operated to discharge thesame and will recommence the winding of a new cop without any attentionon the part of the operator.

In the accompanying drawings Figures 1 and 2 are views, from oppositesides, of my improved cop winding machine, aportion of Fig. 2 beingrepresented in section. Fig. 3 is a plan View of my machine, and Fig. 4a cross section of the same on line 4-4 of Fig. 3.

Fig. 5 is a bottom view of the table of the machine to show themechanism underneath, and Figs. 6, 7 and 8 are detail Views.

A denotes a metal bench or table mounted 39 upon legs A and providedwith a suitable standard a in which is mounted the driving shaft Bprovided with fast and loose pulleys b and b, the gear wheel 0 and thehead or disk d. The loose pulley b is provided with 3 5 a gear wheel bmeshing with a second gear wheel 6 on a short shaft journaled in the arma of the standard a, and provided with the Worm e meshing with a wormwheel F mounted on a transverse stud f attached to the 40 standard a,and rigid with which are the cams f f The table A is also provided witha short standard a havinga suitable guide-way in which is mounted thesliding bracket G journaled in which is a sleeve or hollow shaft 5 gprovided with a head or disk g. The gear wheel 0 on the shaft B mesheswith a gear (wheel 0 on a shaft 0 which is journaled in an arm a of thestandard a and which has splined thereto a second gear wheel 0 mesh ingwith a gear wheel 0 on the shaft 9. The

gear wheel 0 is rigidly mounted on a sleeve to which is attached acollar 0 between which and the said gear wheel 0 extends an arm of thesliding bracket G so that as the said bracket moves to the right or leftthe said gear wheel will move therewith so as to keep it in constantmesh with the gear wheel a on the shaft g. The cam f is embraced by ayoke h on a bar H which has a right-angular arm h which is connected bya pin 71. with the base of the sliding bracket G so that as the said camis rotated with the worm wheel F the said bracket will be moved to theright or left, as will presently appear. The rotary disks or heads cland g are separated from each other, as more clearly shown in Figs. 1and 3, and serve as walls to form a recess or chamber in which thedisk-shaped cop is to be wound. Passing through the sleeve or hollowshaft g is a pin I which serves as a spindle upon which the cop is woundand which, when the sliding bracket G is moved to the right (Figs. 1 and2), will be withdrawn from the cop which latter, upon being released bythe movement to the right of the head or disk g with the sliding bracketG, will be free-to fall into a chute or receptacle 00 below.

The pin I is provided at its outer end with a groove iwhich isengaged bya lug or arm j of a leverJ pivot-edat its lower end between horizontallyextending lugs or projections a on the standard a said lever being alsopivotally connected with lugs or projections g on the sliding bracket G.The upper end of the lever J has an abutment, herein shown as a sorewj',which engages the head 2" of the pin I so that the said abutment and thearm j will move the said pin out and in with the said sliding bracket,and the said pin will 0 thus, at the proper time, be withdrawn from thehead or disk g to disengage the cop and will then be returned for thewinding operation. As the yoke h is moved inward, or to the left inFigs. 1 and 3, the pin I will be projected through the head or disk gand by engaging the thread (which latter will be drawn across its end)will take hold of the same and force it into contact with the rotaryhead or disk (Z so that when the said head or disk d [00 is set inrotation the thread will immediately begin to wind upon the inner end ofthe said pin.

Mounted on the shaft 0 is a small cam c which engages an arm K on asmall rockshaft is journaled in a sleeve L formed integral with orrigidly secured to a lever M pivoted on the shaft 0; the said rock-shaftbeing provided at its forward or inner end with a thread distributorwhich extends between the rotaryheads or disks dand g and which servesto traverse or distribute the thread between the said disks. The lever Mis connected at its upper end bya link m with the rear end of a lever Npivoted on a post n attached to the bracket a or an arm thereof, saidlever N carrying at its outer or forward end a presser wheel a whichcomes between the rotary heads or disks d and g and thus rides upon thethread being wound and serves to compress it and make it wind compactly.The forward end of the lever N is drawn downward, to keep the presserwheel 01 against the th-read,in any suitable manner; a weight nsuspended from the forward end of said lever being herein shown as themeans which I prefer to employ for this purpose.

The cam f is engaged by an arm or tappet O secured to asmall shaft 0extending transversely through the bracket (1 and provided at itsopposite end with a depending arm 0' which engages a slide P providedwith a spring-pressed catch p. A spring q, connected with the arm 0 andthe standard a serves to retract the said slide and to hold the arm ortappet against the cam f The slide P moves longitudinally in a suitablegroove formed in the table A, and, contiguous to the said slide in thesaid groove, is a second slide R provided with a pin or standard 0*carrying aloop r through which the belt passes and which loop serves asa belt shipper to transfer the driving belt from the fast to the loosepulley, and vice versa, as may be required. The said slide R is providedwith a block T which, at times, is connected by the spring catch 19 tothe slide P (said catch being pressed against by a plate spring 1)) sothat as the said slide P is moved toward the left in Fig. 3, or to theright in Fig. 2, the belt may be transferred from the loose pulley b tothe fast pulley b, or said belt may be reversely transferred on theinward movement of the said slide R. Beneath the table A is a lever Swhich is provided with a pin 8 extending upward through a slot in thesaid table and engaging the slide R; springs s and 3 attached to theopposite ends of the said lever S serve to move the said lever in such amanner as to retract said slide R, or to move it to the right in Figs. 1and 3. To the underside of the bed A is attached a small L-shaped plateor bracket T the base of which is provided with a cutting block tofvulcanized fiber or other suitable material; and in a suitable guidewaybeneath the said bed is arranged a thread severing knife W,

which is engaged by a pin 8 on the lever S, so that when the slide Rcarrying the belt shipper is moved outward to transfer the belt from thefast to the loose pulley the said knife will be forced against the saidcutting block to sever the thread; or if the thread be not severed, itwill be held tight by said knife so I that when the thread again beginsto wind it will immediately be broken. The spring 8' connected with thesaid pin 8 and with atailpiece w of the knife W, serves as a yieldingconnection between saidknife and pin so that the latter is free tocontinue its movement with the lever S after the knife is in contactwith the block t.

The lever M is provided with a depending arm hi having a toe orprojection m, herein shown as a screw tapped in the lower part of saidarm, the said toe or projection being art ranged to engage the catch penthe slide P,

and owing to the fact that the said lever M is connected by the link mwith the lever N it will be seen that as the forward end of the lastnamed lever is forced upward by the accumulating thread beneath thepresser wheel n the said toe or projection Will be caused to 1 engagethe said spring catch when the lever N is lifted far enough; and whensufficient thread has been wound to make a cop of any desired size thesaid toe or projection will force the said catch inward and releaseitfrom the block W on the slide R, and the latter, which in the meantime has been held outward by the said spring catch, will then beretracted by the springs s and :5 operating on said slide I through thelever S and will thus transfer the belt from the fast pulley b to theloose pulley b and thereby arrest the rotary movement of the shaft B andthe rotary heads or disks d and g receiving motion therefrom; the lastnamed head or disk, it will be understood, beilgg rotated through thetrains of gears c, c, c, c

The operation of my improved cop winding machine is as follows: In firststarting the machine the end of the thread is caught between the innerend of the pin I and the rotary head or disk d and the machine is thenstarted by running the driving belt on to the fast pulley b, therebyimparting rotary movements to the heads or disks (1 and g and causingthe thread to accumulate on the pin or spindle I which rotates with thesleeve or shaft g through which it passes. As the thread is woundbetween the said heads or disks on the said pin I it is continuouslydistributed back and forth by the thread distributor 7c and is solidlycompressed by the presser wheel n borne down by the weight attached tothe lever N. When suflicient thread has accumulated between the rotaryheads or disks to raise the presser wheel at and the lever N by which itis carried far enough to cause the too or projection m at the lower endof the arm m to engage the spring catch 19 on the slide P and releasethe said catch from the block r? on the slide R, the springs s and sacting on the said slide B through the lever S, as hereinbeforedescribed, will retract the said slide and transfer the driving beltfrom the fast pulley b to the loose pulley 19, thereby stopping therotary movements of the winding mechanism. The gear wheel b rotatingwith the loose pulley I), now imparts movement to the gear wheelewithwhich it meshes and which in turn sets the worm e in motion therebycausing the worm wheel F and the cams f and f moving therewith torotate. The rotary move-,

ments of the cam f imparts movement to the yoke h of the bar H andshifts the said bar to the right (Figs. 1 and 3) thereby moving thesliding bracket G to the right and releasing the rotary head or disk 9from the cop which, when the pin Iis moved far enough outward, is freeto fall by the action of gravity into the receptacle beneath. Duringthis operation the cam f which, through the arm or tappet O, shaft 0,and arm 0, governs the movements of the slide P, has caused the saidslide to move backward or to the left in Fig. 2 so as to engage thespring catch 19 with the block 4* on the slideR and the said slide P isagain moved outward, or to the left in Figs. 3 and 6; by the time thecam f has performed its revolution and has thus returned the slidingbracket G, the rotary head g and pin I carried thereby to their firstpositions; so that the belt shipper carried by the slide R is now againmoved to the left (Figs. 1 and 3) and has transferred the driving beltfrom the loose pulley h to the fast pulley (9, thereby arresting themovements of the worm wheel F and the cams connected therewith andsetting the winding mechanism again in operation. The spool U from whichthe thread for the cops is drawn is herein shown as being supported byan arm V attached to the table A, the thread being led upward from thespool through a guide "0 attached to said arm Vand thence throughsuitable thread guides or eyes m m on the sleeve L to the rocking threaddistributer in extending between the rotary heads or disks d and g.Instead of using the cams f and f for operating the pin I and themovable head or disk and for governing the movements of the beltshipping mechanism, these devices may be operated from other equivalentrotating parts (as eccentrics or cranks) moving with the wormwheel F, aswill be readily understood.

Having thus described my invention, I claim and desire to secure byLetters Pat ent 1. In a cop winding machine, the combination with arotary head or disk and a second rotary head or disk movable toward andfrom the first disk or head, of an endwise movable pin arrangedcentrally of the said disks or heads and extending across the spacebetween them, a thread distributer also arranged between the said disksor heads, and means for rotating the said heads or disks,

for vibrating or reciprocating the said thread distributer and formoving the said pin and the said movable head or disk outward and inwardat times.

2. In a cop winding machine, the combination of a driving shaft providedwith fast and loose pulleys, a rotary head or disk on the said drivingshaft, and a second rotary head or disk normally separated from thefirstnamed head or disk, a shaft by which the last-named head or disk iscarried, a train of gearing connecting the last-named shaft with thedriving shaft, a movable bracket in which the shaft carrying the movablehead or disk is mounted, an endwise movable pin extending through theshaft carrying the said movable head or disk and crossing the spacebetween them, a thread distributingmechanism, a worm, a worm wheel, agearing connection between the said worm wheel and the said loosepulley, means operated from said worm wheel for moving the said slidingbracket and the said pin, a belt shipping mechanism, and means, alsooperated from said worm wheel, for controlling the operation of the saidbelt shipping mechanism in transferring the belt from the loose to thefast pulley.

3. In a cop winding machine the combination with two rotary heads ordisks which in their normal positions are separated from each other adistance equal to the thickness of the cop to be wound, and one of whichdisks or heads is movable toward and from the other, a driving shaftcarrying one of the said rotary heads or disks and which driving shaftis provided with fast and loose pulleys, a train of gearing connectingthe said driving shaft with the other of said rotary heads or disks tooperate the latter, a thread compressing wheel or device to bear uponthe cop being formed and compress the latter, a belt shipping mechanismfor transferring the driving belt from the fast pulley to the loosepulley and vice versa, a cutting mechanism connected with the said beltshipping mechanism, and a mechanism for governing the action of the saidbelt shipper by the accumulating thread of the cop; whereby when a copof any desired size has been formed the said governing mechanism may beoperated to release the belt shipper and transfer the driving belt fromthe fast to the loose pulley and thus suspend the winding operation.

4. In a cop winding machine, the combination with two rotary heads ordisks normally separated from each other during the winding operation,and one of which is movable toward and from the other, of a threaddistributer and a presser wheel or device hearing upon the accumulatingthread, mechanism for rotating the said heads or disks, and a stopmotion, for said rotating mechanism, controlled by the said presserwheel or device, the position of the latter being governed by theaccumulating thread.

IIO

ro trolled by the said presser wheel or device,

the position of which latter is governed by the accumulating thread onthe cop, and a knife for severing the thread.

In testimony whereof Iaffix my signature in presence of two witnesses.
